Screening Chinese Stocks by Position Increases, Size, Market Cap, and Profitability

Summary

The post describes a Chinese equity screen seeking companies with no losses, scale above a stated minimum, market capitalization below a stated ceiling, and a recent position increase greater than 5%. It frames the approach as a short-term filter based on position changes, company scale, market value, and profitability. The accompanying example then proposes adding longer-term measures, including return on assets, return on equity, and dividend yield, as refinements.

The post warns that relying on recent performance can overlook longer-term strengths and may produce errors during sharp market moves. It provides no backtest results or evidence that the criteria predict returns. Its prose and sample code also differ in places, including the market-cap thresholds and the added profitability and dividend filters, so the intended screening rules should be checked before implementation.

Key ideas

• The initial screen selects stocks with a recent position increase above 5%, a minimum scale, and market capitalization below a stated ceiling.
• The post also requires companies to have no losses.
• Suggested refinements include profitability measures and dividend yield.
• The author cautions that the screen emphasizes recent conditions and may miss longer-term performance.
• The example contains discrepancies with the stated criteria and provides no performance validation.
